Site cabin EICR

Hi Benyamin,

I do not understand your question. 

I would love for you to specify more (focused). Thanks

I assume from your post English is not your first language, and that perhaps you are not familiar with UK building site and wiring practice.

Let me know if the following does not make sense.

First, a site welfare cabin is a metal box/ building,  resting either on metal feet, wooden sleepers, or just on forklift pockets and skids,  as a minimum probably containing a toilet and basic washing facilities. However larger ones have can have more 'rooms' and include a small shelter/cooking/ eating area. It is dropped at a building site, or at the roadside, so that a mobile workforce have some basic facilities while mending the road or whatever. At the end of the job it is put back on the lorry and driven to the next project. electrically it may have little more than lights, or it may include a water heater, space heating and provision for microwave and kettle etc.

The poster has been asked to perform an EICR - an electrical safety inspection. He is asking what value of electrode resistance is acceptable for a mobile  generator supplying such a thing.

That will depend on the arrangement  of circuit breakers and RCD (ground fault breaker in American) that are used to protect the users of the portable building,  and what else is supplied by the generator.
